The elder Chavez had suffered a cut over his left eye in training, yet went ahead with the fight, during which the wound opened up early and bled profusely on the way to a fourth-round stoppage victory for De La Hoya.

Saying that he did not want the same thing to happen to Chavez Jr., Salazar said why give Vera “advantages?”

The injury not only shelved Chavez Jr.’s bout with Vera, but also those on the undercard, including a junior middleweight fight between Vanes Martirosyan and Demetrius Andrade for the WBO’s vacant belt.

Concerning a new date for the show, Top Rank President Carl Moretti said, “We’re working on that right now,” adding, “We’re waiting on HBO to give us a new date.”

Chavez was to have been out of the ring for nearly a year by Sept. 7. His last bout was unanimous decision loss to RING middleweight champion Sergio Martinez last September.

Martirosyan, 27, is coming off a second-round knockout of Ryan Davis in June that followed a draw with Erislandy Lara in November of last year.

A 2008 U.S. Olympian, Andrade, 25, was last in the ring for a unanimous decision over Freddy Hernandez in January, after a streak of four consecutive stoppage victories.
